lowered and then locked in its working position as has hitherto been necessary.

l also desire to provide a bobbin Winder with a novel device for automatically releas= ing and throwing up a spindle or .spool when this has been lled with a predetermined amount of thread or yarn ;'-the inv vention contemplating a novel relation of the spindle with the parts which normally held 1t in a working position.

I further desire to provide a novel form of bobbin holder which will serve as a brake to prevent rotation'of a full bobbin after this has been 'thrown from a working to an inoperative position and that in spite of the continued operation of the machine.

These'objects and other advantageous ends I secure as hereinafter set forth, reference 'being had to the accompanying drawings, in which,-

" extends a framework consisting ,of a rod Figs. 11 andl12 are respectively a side and an end elevation of a slightly modified form of the holding means for the free end of the 'bobbin spindle.,

ln the above drawings,v1 and 2 represent a pair of standards connected at the to-p by a transverse table or plate 3, from the center of which depends a. bracket or hanger 4.` i

The lower end of this latter provides bearings 9 for a pair of spindles 5 and 6, whose opposite ends are carried in bearings 7 and 8, supported by or formed as part of the two Standards 1 and 2. These spindles in turn support tubes w on which is woundY the yarn or thread of a pair of supply bob* bins a" rllhe bearings 7, 8 and 9 are so formed as to' permit of the convenieifft insertion and removal of the spindles 5 and 6. yProjecting upwardly from the plate 3 of the frame of the machine are a pair of parallel, vertical standards 24 and 25, providing bearings for a horizontal spindle 26, on which is mounted a xed pulley 27, although obviously any other suitable driving means may be employed for said spindle. Adjacent they outer faces of the two standards 24 and 25 there are fixed to the spindle 26 a pair of leather covered driving rollers or pulleys 29 and 30, over each of which 31, a bar 32 preferably parallel to said rod and having its ends 33 turned at right angles and a second rod 34 extending between the extremities of said ends, parallel to the rod 31. rl`his latter with the bar 32' is rigidly fixed to the standards 24 and 25 which also -providey bearings for a longitudinally slidable rod 35, which at each end has fixed to it a head 36 carrying a thread guide 37. The rod 34 has fixed to it, opposite each of the rollers 29r or 30, a porcelain -or'other smooth hard thread guide 38. Each end of the rod 31 has loosely mounted on it a movable frame consistingof a pair of substantially parallel arms 39 and 40 19@ engaging said rodand rigidly connected to or integral with a member 41 extending at right angles to theni. rllhis member projectsbeyondthe-arm 40 and is forked 'to provide bearings 42 and 43 (Fig. 7) for a-105 shortV spindle 44 to one of whose ends is fixed a collar 45 and an arm 46 constituting an'operating handle. The collar 45 has projecting radially from it a bobbin spindle 47 and the short spindle 11@ 44 is acted on by a spring 48 mounted on it between the bearings 42 and43, in such manner that it tends to turn into a position in which the bobbin spindle is elevated at an angle of about 60o to the horizontal. For

j limiting this movement, however, I provide a transverse pin 49 in the rear end of the spindle 44 and also a pin 50 projecting rearwardly from the bearing 42, in position to be engaged by saidpin 49 when the bobbin spindle occupies its desired elevated position. The arm 39 of this spindle-carrying frame projects forwardly beyond the member 41 and the underside of its front extremity has a transverse recess 51, Fig. 9, so as to be capable of receiving the free end of the bobbin spindle 47, although it is to be particularly noted that this latter is so set in the collar 45 or is otherwise so supported that it normally tends to occupy a position on the forward side of the line of said recess. Said movable frame has fixed to it on or adjacent the arm 39 a plate 52 downwardly and forwardly curved to one side of and below the recess 51, beyond which it projects for a distance sufficient to engage and limitv the downward movement of the bobbin spindle 47.

The bar 32 is-preferably, though not necessarily,- of rectangular section and has a straight edge extendingimmediately adjacent and parallel with the cylindrical surface of the driving rolls 29 and 30v which are preferably covered with leather or other equivalent material having a compara-tively high coefiicient of friction. A flat face of this bar extends outwardly from the surface of each of said rolls and on it, opposite the end of the arm 39, I mount an inverted U-shaped body of strip material 53, Fig. 5, designed to guide the end of the bobbin spindle under the extremity of said arm and to retain it in the recess thereof under normal conditions, when it is lowered as hereafter explained.

A knife blade 54 is preferably mounted` on the ro'd 32 and for tlievsake of convenience I have shown it as held' in place by the same bolt 55 which retains the guide piece 53 in position. It may be noted that if desired, said blade or its sup-porting structure may be utilized as shown in Figs. 11 and 12, to perform the functions of the guide and retaining piece 53, since such a blade may be mounted on the standard 25 adjacent the end of the arm 39 and the plate 52 so as to serve to direct the bobbin spindle under the extremity of said arm as well as toretain it in the recess thereof when the spindle is lowered.

v For automatically causing raising of the 'frame 39v40-41 and freeing the bobbin spindle so that it may move to its elevated p'o. sition under the action of the spring 48, I

form on said arm 40 a downwardly project-` For 'supporting this lever I p ovide the standard 24 with a horizontal sot 60 and into this slidably extend the pivot or fulcrum bolt 61`on which said lever 58 is mounted, adjusting the bolt in the slot by a pair of screws 62 and 63, and thereafter clamping it in a given position by its nut 64. The second arm of the lever 58, (which 4is preferably of the first order) has its upper face formed with a series of notches or teeth 65 for the reception of one end of a coil spring 66, whose opposite end is connected to the standard 24 by a bolt or pi-n 67 so as to at all times press the lug 59 of said lever toward said finger 57. The force exerted by the spring may be varied lbyshifting it from one of the notches to another at a different distance from the fulcrum bolt.

Asa result of this construction the spring of the frame 39-40-141 and therefore the diameter of the filled bobbin before the finger passes over the lug 59 and it is automatically thrown up and out of action by the spring 66.

In order to evenly distribute the thread upon a bobbin mounted on the spindle 4 7, I reciprocate the rod 35 with the yarn guides 37, by means of any suitable devlce driven from the shaft 26." In the-present instance this consists of a Worm 68, fixedy to said shaft and meshi 0 with a worm wheel 69, mounted on a spind e supported in Vbearings 71 projecting upwardly from the topplate 3 of the main frame. Said spindle also has fixed to it a cam 72 designedA to coperate with a pin 73 on one arm 74 of a lever whose second arm has fixed integral with or attached to it a weight 7 5- at all times acting to maintain said pin and cam in engagement.

lThe arm 74 is formed with a longitudinally bins m are mounted on the spindles 5 and 6 respectively and the latter are placed in the bearings 7, 8 and 9, as shown in Fig, 1. Thereafter suitable braking devices are applied to the bobbin and the end of the thread from the supply :y bobbin is run through a tension device up around the porcelain or other guide 38 and thence through the yarn guide 37. An empty bobbin spool is placed on the spindle 47 while this is held by' its spring in an upwardly inclined position and power is applied to the main shaft 26 to'turn the driving rollers 29 and 30. Each handle 46 is then pressed downwar'dly and at the same time given a limited rotary movement which turns the spindle 44 so that the free end ofthe bobbin spindle iSv-brought into engagement with the plate 52 immediately in front of the arm 39 and thereafter the frame 39-40-41 is swung downwardly.

The inverted U-shaped piece 53 thereupon acts upon the free end of the bobbin spin` dle t0 force this rearwardly S0 that when the cylindrical surface of the bobbin finally' comes into engagement with the surface of the driving roll 29, said spindle end has been bent rearwardly suiiiciently to enter the recess 51 in the. arm 39. The end of the thread is now introduced between the bobbin spool and the member 41, and the shaft 26 is turned in a direction such as to cause said thread to be at once drawn inbetween the driving pulley and said bobbin. Owing to the proximity of the bar 32 and also to the upwardly flowing current of air between the bobbin and said bar caused by the rotation of the bobbin spool, this thread end is caused to turn upwardly between said parts and to thereafter be carried around between the bob'bin and the driving roll so that it is almost immediately held fast a-nd thereafter wound 0n the bobbin as said roll continues to turn. being evenly distributed lby the reciprocation ofv the rod 35 under the action of the cam 72.

As the thread continues to be wound upon the bobbin it is obvious that its 'spindle 47 and hence the frame 39-40-41 is gradually moved away from the driving roll 29, turning around the rod 31 as an axis .and moving the finger 57 up on the inclined lug 59 of the lever 58 until it finally passes over the sharp edge of said lug, whereupon the spring 66 acts through said lever and the finger to continue the upward swing of said frame until the finger comes into engagement with a stop 80, projecting from the standard 24. Such upward movement of said frame allows the bob/bin spindle 47 by' reason ofits tendencyto occupy av posil tion on the forward side of the recess 51 to move out of sald recess so that the spring 48 becomes effectivev to rotate the spindle' 44 'and throw up the bobbin spindle with the filled bobbin to the elevated position shown in dotted lines in Fig. 1. The thread 1 is thereupon cut by being drawn against the knife blade 54 and the filled bobbin is replaced by an empty one, which is broughtl vinto engagementI with'the driving roll andl v dle when the latter is thrown to its supplied with thread as heretofore explained. f

Each bobbin spindle has held to it by means of a set screw, a flanged head 82 having in its face a conical recess designed for the reception of the end of th bobbin. Said recess preferably has a lining 83 of felt or the like, in order that it may serve to retard rotation of the bobbin on the spinraised position.

Obviously the amount of thread wound on a bobbin before the latter is automatically thrown up and out of engagement whereby a single downward and rotary movement of the bobbin controllinghandle 46 suffices to place the bobbin in position to be filled.

Further, the automatic release and throwing up ofthe filled bobbin by reason of the peculiar mounting of the bobbin spindle so that its free end tends to lie to one side of the recess 51, constitutes another valuable feature tending to facilitate the easy and consistent operation of the machine.

The provision of the conical lined bobbinholding head on the spindle 47 assures the stopping of the rotation of the filled bobbin as soon as this is thrown up by reason of the friction exerted on said bobbin by the material in said head.
